If the drill is too difficult with this target size or distance, reduce the distance or increase the target size and work down to 10 yards and 3 inch dots. Once you can do this on demand, your precision skills will be way above average. Practice with a goal of increasing your speed, while maintaining your accuracy. Just blasting at them will not help you a bit.. Perfect practice makes perfect performance.

Remember... The only way you can be successful at this, is to have your sights clearly in focus for each and every shot. Shoot at the center of the dot, not the whole dot. Good luck!
